REINFORCED-CONCRETE PLANK AND SEA-TALL CASING.

To all whom t may concern Beit known that I, J onu JOSHUA MILLER, a citizen of the United States, residing at SanDiego, in the county of San Diego and State of California, have invented a new and Improved Reintorced-Concrete Plank and Sea-lVall Casing, of which the `following is full, clear, and exact description.

My invention has reference to improvements on sea walls, and it consists in the novel arrangement, construction, and combination of parts as herein described and claimed, the objects of the invention heilig to construct sectional casings having means for interlocking the adjoining sections preparatory to pouring, ramining, and otherwise filling the easing to make the completed sea Wall, it being a design of the invention to so relate the elements thereof, that the sections shall be simple to manufacture, that they may be easily assembled preparatory to )lacing the concrete thereon, that they may be maintained in alinement until the wall is completed, that they may be anchored securely to the earth, and that they may be erected without the assistance of skilled labor, it being also a design of the invention to construct-the sections with the metal reinforcements so arranged as to interlock and produce a rigid and substantial casing that may be placed in the water and withstand the pressure t-hereotn preparatory to the coinpletion oit the wall structure. The principles herein related may be embodied into any suitable term, and therefore, for the purpose of explanation, a preferred arrangement with the proper correlativo parts, is shown in the accompanying drawings which form a part ,of this specification.

While simple and etiicient means are herein provided for accomplishing the objects of the invention and the elements shown and described are Well adapted to serve the purposes tor which they are intended, it is to be understood that no limitation is made to the precise structural details exhibited, but that variations, alterations, and modifications, within the scope of the a pended claims, may be adopted if desired, tide essence of my invention comprising a sea wall casing with separate interlocking form sections, and means for securing and maintaining alinement of adjoining sections and opposed walls of each section, to form a casing to receive the plastic material and thefreby form a concrete sea wall, the invention being fully Specification of Letters Patent4 Application led May 6, 1912. Serial No. 695,401.

illustrated in the accompanying drawings, whereon Figure 1 is a perspective view ot' two interloekingr sections ot my reinforced concrete plank and sea wall casing, incorporating the principles of this invention, disclosing the position of the plank, the opposed side walls,

the bonds which connect them, and the position ot" the metal reinforcements therein. Fig. .2 1s a sectional detail view of an interlocking joint of the upper wall casing disclosing the arrangements ot the metal reintorcelnelits therein. F ig. 3 is a perspective and detail view of the interlocking joint at the upper end o'tl the anchoring plank or panel. Fig. -t is a sectional detail view of a portion of a wall section. disclosing the arrangement oi the tying, bonding. and bracing means between the opposed walls of the casing', and the alternation oi the longitudinal metal reinforcements therein.

In the several illustrations similar characters ot reference apply to corresponding parts.

Assuming the kInvention to be embodied in the form illustrated, each section of the casing has central wall or plank l, forming the lower part, and opposed side walls 2, the central and side walls being in parallel planes, and the side walls forming the upper part ot a casing section. Side walls 2 have flange members 3, forming a longitudinal channel 4, therebetween, which engages with tongue member 5 on tlie adjoining edge of the next successive section. Side walls 2 are supported in opposed relation each to the other, and are connected by transverse tie bars 6, which are anchored to horizontal reinforcing rods 7, in the side walls. A cement reinforcement 8 is provided for the tie rods at their entrance to the side walls.

The side walls are provided with vertical reinforcing rods 9, arranged in the center thereof, and horizontal rods 7', are arranged alternately on op osite sides of rods 9. At each edge of the side walls, rods 7 pass to the opposite side of the Wall to form flanges 3 and tongue member 5. This crossed relation of the reinforcing rods, strengthens .the parts correspondingly. In the tongue member the crossed ends of rods 7 are tied to vertical rods 10.

Connecting member 11, unites the u per edge of the lower plank with side Wal s 2, and is formed of concrete. A plurality of vertical reinforcing rods 152, are embedded in.

has flanges 1G, which engage with flanges Iof the casing.

the side wall, and the joints prepared as member 11, some of which eXtend from the bottom of plank l, to the level yof the top ot' side walls 2, and others extend upward a short distance from member l1. In Fig. l et' the drawing, a part of rods 12 are shown, but it is to be understood that the number may be as desired to suthciently reinforce the concrete material to be placed between the walls of the casing. Reint'orcing rods 13 are horizontally disposed between the walls The plank member is formed with a longitudinal channel 14, land a corresponding tongue member 15, on opposite edges-thereof, for connecting adjoining sections and securing them in alinement. Member l1 17 on the next successive section. These tianges overlap when the sections are assembled, and may be coated with tar or other waterproof preparation to form a water* tight joint. In assembling the sections preparatory to pouring the concrete therein, all interlocking joints may be thus prepared with a waterproof coating.

A retaining wall tor the sea, for rivers, and for all waterways may be formed by assembling a sufficient. number of sections of casing as herein described, the sections of the casing being prepared and reinforced described, and then placed in position with the plank member extending into the earth. the section being embedded to the bottom ot aforesaid. The seetimis are assembled by engaging the tongue members ot one section with the adjoining section and then placing the section in position, and so on until a wall casing is completed, and then pouring the plastic material between the side walls until level with the top thereof.

It Will be noted thatl this invention embodies the use of a plurality olf' form sections which are prepared prior to' erecting in the water to form the wall, means heilig provided for uniting the sections to form a continuous wall or casing lor the entire strueture to be erected. the said casing having transverse, vertical, and horif/.ontalj',r die posed reinforcing rods which are. to be einbedded in the concrete material placed hctween the walls ot the casing, thus tirmly j uniting the casing and the material placed therein, into an integral and homogeneous structure.

I claim as my invention:

1. Tn a reinforced concrete retaining wall, a plank of cement or concrete adapted to be, embedded to its l'nll depth into the earth, a connecting member at the top llicrcot', side j walls extending upward lrom Isaid connecting member. transverse tie rods extending between said .sido walls, a. plurality of metal x reinforcing rods disposed within thc space 1 formed by theI side walls., and a cement. body between said side walls embedding said tie rods and reinforcing rods, substantially as set forth.

2. In a retainingwall, the combination of opposed side walls to form a casing, a plankl to extend into the earth. a connecting member between said side Yalls and plank, and a concrete body within said casing, substantially as set forth.

5. ln a easing :for a retaining wall, a plurality ot separate sections, opposed side walls to each section, a connecting member at the bottom ot` the side walls, a panel depending from .said connecting member,` means for securing the opposed side walls in a rigid position, and means for securing the adjoining sections each to the other. substan-` tially as set forth. A

6. ln a casing 'for a retainingwall, a pll1 rality ot sections, each o't said sections coinprising'a central and two side plates, cach ot said sections having a projection on one end ot cach ot said j'ilates, and a corre- Ispending seaty at the other end whereby the sections may he locked together, substantially as set forth.

7. ln acasing `for a retaining wall, a pln` rality ot sections adapted to be assembled into a continuous structure, and a plurality ol` flanges on each section so interlocking with each other and overlaj'iping to torni watertight joints and form a continuous structure to receive a cfncrcte body, sub- Istantially as set forth.
